The following Clustershell commands were used to
construct a first SVM that just serves iSCSI. Additionally; the SVM is used as
an Active Directory Domain Tunnel (to allow AD authentication to Cluster and
SVM); and a DMZ Broadcast Domain has been implemented (for VMs that might be in
a DMZ and need to use SnapDrive for instance). This is just a SIM lab example though,
and could be described as an advanced setup - it is not meant as a guide for
how to do things in the real world.

Note: For testing,
vsadmin has been allowed SSH login, also a Cluster Management LIF has been
created in the DMZ.

i: The Current
Network Setup

The SIMs in the 2-Node cluster have 7 vNICs each. The
current setup of ports to Ipspace and Broadcast Domain, and LIFs, is
illustrated below.

Note: In the images
below, a square represents a physical port, circles are LIFs (logical
interfaces).

Image 1: Ipspace = Cluster, Broadcast Domain = Cluster; and LIFs

Image 2: Ipspace = Default, Broadcast Domain = Default; and LIFs

ii: The New
Network Setup

No changes are made to the Cluster broadcast-domain. We
split the Default broadcast-domain into Default, iSCSI-1, iSCSI-2, and DMZ.
